TL431BCD datasheet by Texas Instruments

TL431BCD Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for TL431BCD?
  The recommended operating temperature range for TL431BCD is -40°C to 125°C.
• How do I ensure stability when using TL431BCD as a voltage reference?
  To ensure stability, it's recommended to use a bypass capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to keep the impedance of the output circuit low.
• Can I use TL431BCD as a voltage regulator?
  While TL431BCD can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. For voltage regulation, consider using a dedicated voltage regulator IC.
• What is the minimum output current that TL431BCD can supply?
  The minimum output current that TL431BCD can supply is 1mA, but it's recommended to use an external buffer amplifier if you need to drive a load with high current requirements.
• How do I adjust the output voltage of TL431BCD?
  The output voltage of TL431BCD can be adjusted by connecting a resistor divider network between the REF and ADJ pins, and adjusting the ratio of the resistors to set the desired output voltage.
